Daffodils form a group of large-flowered members of the genus Narcissus.
Daffodils grow perennially from bulbs. In temperate climates they flower among the earliest blooms in spring: to this extent daffodils both represent and herald spring. They often grow in large clusters, covering lawns and even entire hillsides with yellow. All daffodils have a central trumpet-shaped corona surrounded by a ring of petals. The traditional daffodil has a golden yellow color all over, but the trumpet may often feature a contrasting color. Breeders have developed some daffodils with a double or triple row of petals, making them resemble a small golden ball. Other cultivars have frilled petals, or an elongated or compressed central trumpet.
